This map seems to crash my server when it loads :( it does work on listen server, but only if you start a listen server on the map. One that is already running and changes to this seems to crash. Probably the same for dedicated servers, but not tried.

A pretty damn challenging map… I come from TFC where jumping/skills puzzles are very common - and I found this map pretty difficult.

It's nicely designed, but definitely a skills map for the expert players. I can see many new players getting frustrated and then bored with this quite quickly.

At least you've put checkpoints so we don't have to go back to the beginning, but due to the difficulty of the map it may be a good idea to have one more often - one for each 3 jump sections done rather than 6.

Still, the light function in the end room is nice. I'm glad you kept it to just lighting and not traps. Traps would make this already hard map impossible :p

I put the light switch just for fun. About the difficulty, you right this map has made for the expert players. It's a good challenge for those who say "there is nothing that I can't beat in less than 1 minute". However, the smart players can beat this map less than 1min, because they go and boost eachother to get into the hole on the ceilling. So I'll fix this bug with the good old clip brush. And that annoying error, I don't know why it is crash the game I checked the map many times. Perharps the big outdoor cause the error.
